Paul Scheer Had a Creepy Jack Nicholson Impersonator as His Best Man (VIDEO)

On the surface, it sounded like a fun idea. Paul Scheer hired a Jack Nicholson impersonator to act as his best man at his wedding. He talked about how wrong it ultimately went, though, on 'Late Night' (Weeknights, 12:37AM ET on NBC).

Scheer had written up a pun-filled script for the guy to recite, but he ultimately forgot everything he was supposed to say. That's when Scheer and his guests learned that this is a guy you do not want to allow to ever go off script.

He said "Yummy!" over and over again, cracked a joke about coming from a pool party at Roman Polanski's house and then tried to set himself up to get hugs from the people there.

"Now my mom is giving a toast and there's weird Jack Nicholson impersonater behind my mom just going like, 'Hugs? Hugs? Hugs?'" Scheer lamented. At least it makes for a great story now.
